SECTION 1
WEAPON UNIT GUIDE
1.1 PURPOSE
The inspection, maintenance and Gleaning of ballistic equipment Is
an important part of proof technique. Weapons used for official acceptance
tests shall be inspected, maintained and cleaned in accordance with the prac-
tices outlined herein. Complete records of the wear history of weapons should
be maintained for reference as a possible aid in the interpretation of ballistic
results. All weapons shall be controlled by regular Inspection and maintenance.
1 . 2 EQUIPMENT
Equipment listed in the applicable Inspection Equipment List shall
be used.
1.3 FIRING -PIN MEASUREMENTS
1.3.1 Before comparability in test conditions can be established between
stations, it is necessary that attention be paid to firing-pin diameter and
contour, firing-pin protrusion and firing-pin indent of the test weapons and
test actions. These measurements shall be made .before a weapon or test action
is placed in service, after misfires, pierced primers or flowbacks; or whenever
a part replacement has been made in the bolt assembly.
1.3.1-1 Firing-pin diameter shall be checked with a micrometer, however,
when difficulty is experienced with an unusual series of primer defects, the
contour of the firing-pin point should be checked with a templet or visual com-
parator. The diameter of the firing-pin hole in the face plate should be
checked concurrently. A loose fit between firing-pin and firing-pin hole, due
to improper diameter of either or both, may cause punchouts of the primer and
loss of sensitivity due to eccentric blow.
1.3.1.2 Firing-pin protrusion must be checked frequently to insure against
pierced primers or misfires. Pin protrusion is measured with a dial gage of such
construction as to be suitable for the particular weapon or action involved.
1.3.1.3 Firing-pin indent shall be measured by placing a copper pressure
cylinder in a fixture (drawings of cylinder and fixture are referenced in the
applicable Inspection Equipment List), the fixture is then inserted in the cham-
ber of the weapon, the bolt is closed and the firing-pin released. The cylinder
is then removed and the distance from the bottom of the indent to the undeformed
surface of the cylinder is measured using a dial gage. A point micrometer graduated
to .0001", may also be used. If a micrometer is used, the cylinder shall be

j before indentation is made, and again after indentation between the
01 th-;- Indent and the opposite end of the cylinder. This measurement
tr;-.! from the original measurement, the difference shall be the primer
C.'OTE: Firing-pin indent and firing-pin protrusion shall be as shown In
the detailed sections of this regulation. )
1.^ MEASUREMENT OF GUN CHARACTERISTICS
l.'r.l Headspace. The headspace of all test and service weapons shall be
irea the first time they are put in use during any shift or when fitting new
-lE to ilxed receivers. All test and service weapons shall conform to the
psce tolerance specified in the detailed sections of this regulation.

1.5.1.3 A succession of clean cloth patches is then run through the bore
,1 it is completely dry and clean. If barrel Is not to be used in the immediate
L re, a clean patch is immersed in oil and run through the barrel so that a
f t film covers the chamber and bore.
1.5.1.4 Whenever the construction of the gun permits it, the bore is
^ned from the breech. When it is necessary to clean from the muzzle, special
r is necessary in cleaning the chamber in order to remove the dirt, lint and
itles deposited therein during cleaning of the bore.
1.5.2 Small metal parts are cleaned by immersing in a bath of solvent or
!,ner and scrubbing vigorously with a brass brush. Large metal parts are
by wiping with a cloth soaked in solvent, cleaner or light oil.
1.5.3 Frequency of lubricating and cleaning.
1.5.3.1 Special test weapons (Receivers, Pressure Gages, etc.)
1.5.3.1.1 The bore and chamber are cleaned and lightly oiled at the close
; ach shift in which the weapon is used. All exposed parts of the receiver are
>d with an oily cloth.
1.5.3.1.2 Once each, week, each test action in current use is completely
lantled, inspected, cleaned and lubricated.
1.5.3.1.3 Metal fouling is removed when it becomes too thick. The time for
>val of such fouling is left to the judgment of the gunsmith, but the barrel is
>r allowed to foul to the point where the fouling begins to scale off.
1.5.3.2 Service Weapons
1.5.3.2.1 The chamber and bore are cleaned at the close of firing on each
't in which the weapon is used.
1.5.3.2.2 The receiver and bolt groups of each weapon are completely dis-
jmbled and cleaned at the close of firing on each shift or after 1,000 oar-
Lges have been fired, if more than 1,000 cartridges be fired per shift. The
*er and trigger groups of automatic weapons are completely disassembled and
med as needed. Complete disassembly of the trigger and hammer groups each
is unnecessary.
145.3.2.3 The weapon is lubricated after each cleaning. Lubrication is
Lied to all moving parts and to the bore.

1.6 REMOVAL OF METAL FOULING
1.6.1 The solution used for the removal of metal fouling consists of the
following :
Ammonium per sulphate, USP 1 02.
Ammonium carbonate, USP 0.5 oz.
Ammonia water (2&fo NH3 oz. vol.)
Spec. O-A-451, Class B 6 oz..
Water 4- oz.
It is recommended that this solution be prepared as required.
NOTE: This solution is very corrosive when allowed to dry on a metal
surface or if brought in contact with a hot surface of a barrel.
Great care should be exercised to see that it does not come in
contact with blued metal or with gun actions.
1.6.2 To remove metal fouling, the barrel should be thoroughly cleaned. To
remove the last traces of oil, a single cartridge should be fired through it Just
before introduction of the fouling solution.
1.6.3 A tight fitting stopper is inserted into the bullet seat, and the foul-
Ing solution poured into the barrel until it is filled completely up to the muzzle.
1.6.4- If the solution does not completely fill the barrel, a line of corrosion
will be formed. Some method must therefore be used to assure the barrel remains
completely full. (A rubber tube slipped over the muzzle, a crater of grease built
up around the muzzle, or the constant observation and addition of solution as it
evaporates. )

SECTION 2
REFERENCE COMPONENTS AND REFERENCE AMMUNITION
2.1 PURPOSE
Reference cartridges with assessed values, hand-loaded or machine -loaded ,
are used to establish velocity and pressure levels by which test equipment service-
ability and performance may be determined. The correction factors (deviations
from assessed values) shall be applied to results of velocity and pressure tests.
2.2 EQUIPMENT
Equipment listed in applicable section of the appropriate Inspection
Equipment List shall be used.
2.3 STORAGE AND CARE OF REFERENCE COMPONENTS AND AMMUNITION
2.5.1 An inventory of all reference components (bullets, primed cases and
propellant) and reference cartridges (machine-loaded) shall be maintained to show
the quantities on hand and the quantities used each month. As additional components
or cartridges are needed, they shall be requisitioned from the responsible instal-
lation. Bullets and primed cases must be handled with care to prevent damage to
dimensions because of the close tolerances to which they are made. Bullets and
primed cases may be stored within the building, preferably at a temperature of
70F. Machine -loaded cartridges shall be stored in an ammunition magazine.
2.3.2 Reference propellents are packed In hermetically tight containers and
stored in' dry, well ventilated magazines reserved for this purpose. When the pro-
pellant Is protected In this manner it may be stored for an unlimited time without
any change In moisture content.
2.4 MAINTENANCE OF MOISTURE CONTENT OF REFERENCE PROPELLANT
2.4.1 A moisture control chart shall be maintained showing the moisture-
volatile content on each propellant sample of current use. When a sample of pro-
pellant is re'moved from the sealed container, the ideal handling method is to em-
ploy small containers which can be closed quickly and tightly. Any handling method
should be of such a nature as to create the least possible change in moisture-
volatile content. The containers shall be identified and the moisture control chart
shall indicate whenever a new container Is opened. While the propellant is being
used from one container, the moisture-volatile content shall.be determined at lea^t
once each week'. It shall also be necessary to determine the moisture-volatile con-
tent on the second container, so if the moisture-volatile content of the first
sample falls outside the control limits, there will be a replacement available for
use.

tion shall be made in accordance with test method contained in MIL-STD-286 to
determine whether further processing is necessary or if the propellant may be used.
2.5 OPERATION OP HANDLOADING REFERENCE CARTRIDGES
When handloaded reference cartridges are required, the cartridges shall
be handloaded in a room having a controlled temperature of 70P. + 2F. , and a
relative humidity of 60 percent, + 5 percent.,
2.5.1 Upon removal from the storage area, all reference components shall be
conditioned at a constant temperature of YOF. + 2P., for a minimum of twenty-
four hours.
25.2 Whenever propellant samples are received in more than one container
and it 'is required to obtain results on the blend, the samples shall be thoroughly
blended by pouring the propellant through the blending tower no less than five
times,
2,5.3 Components (primed cases, bullets and propellant) are placed at an
accessible point to the balance. Cases, are placed in a recessed holding block,
primer-end down. The amount of propellant exposed to the atmosphere should always
be held bo a minimum.
254 Balance is leveled and the correct weights applied for the propellant
charge'to be weighed. Propellant shall be weighted to ,0.1 grain. (When necessary
to check weight of propellant in a cartridge, it shall be checked to the nearest
0,01 grain). Balance should be checked at bi-weekly intervals.
255 The funnel Is placed in the mouth of the case and the propellant poured
slowly' and evenly through the funnel into the case, preferably J rom * he ^ f
approximately three inches above the mouth of the case. Care should be taken that
a minimum amount of propellant strikes the sides of the funnel Propellant shall
be poured in this manner to assure that proper air-space is obtained. The funnel
is removed and an Inverted bullet is placed in- the mouth of the case.
2 *5 6 After the required number of cases has been loaded, the bullets are
removed and then carefully seated to the proper depth, using a bullet-seating press
Each cartridge is then measured for overall length and shall be within dimensions
shown on the applicable drawing.

this section. Lumillne screens are checked for position. It is of the utmost
Importance that the lumillne screens be placed in their proper positions, measure-
ments must be accurate within 1/4", Distance between screens shall "be 25 feet,
2.7,3 Velocity, Chamber-Pressure Firing
2.7.3.1 Twenty copper pressure cylinders shall be measured Individually and
placed in a recessed holding block. Upon completion of the firing, the cylinders
shall be measured again and the decrease in length obtained by subtraction of the
actual readings. The decrease In length obtained for each cylinder shall then be
applied to the appropriate tarage table (a tarage table is supplied with each box
of copper pressure cylinders) and the corresponding chamber-pressure (PSI) shall
be recorded on the test report form In such a manner that the velocity of each shot
can be Identified with the corresponding chamber pressure obtained,
2.7.3.2 The recessed holding block containing the cylinders, the pressure
piston and a sufficient quantity of obturating cups (use a new cup for each car-
tridge) should be placed at a point convenient to the technician.
2.7.3.3 Five warming (fouling) shots shall be fired. To fire the warming
(fouling) shots It shall be necessary to service the velocity, chamber-pressure
assembly with an obturating cup, the pressure piston, and a copper pressure
cylinder. The same cylinder and obturating cup may be used when all warming shots
are being fired, the anvil is screwed down on the cylinder following each shot.
2.7.3.4 The recessed holding block containing twenty cartridges is removed
from the controlled-temperature room or container and placed at a point convenient
to the technician, provided the temperature of the firing room is 70P, + 5F
otherwise the cartridges shall be placed in an insulated box (five cartridges at
a time) which has been conditioned at 70F., + 5F. ( and the box placed at a point
convenient to the technician, the cartridges are then removed singly from the in-
sulated box Immediately before firing. If an Insulated box is not available, then
the cartridges shall be removed singly from the controlled-temperature room or box
and fired. The confcrolled-temperature room or container, or both, shall be main-
tained at 70 P., + 2 P., and a relative humidity of 60 percent, + 5 percent.

2.7.3.5 A dummy cartridge is placed in the chamber of the barrel assembly.
The obturating cup lubricated with oil, SAEM-0 or equivalent, shall be placed in
the piston hole, mouth end down, and partially seated using the stem of the knock-
out tool. The shank of the pressure piston shall be dipped in oil and the oil then
be allowed to drain from the piston. The drop of oil adhering to the bottom of the
piston shank shall then be removed by touching the bottom of the piston shank to
a cleaning patch. The piston shall then be inserted into the piston hole and
pressed down on the obturating cup until the piston has reached its correct final
position. The head of the piston and bottom of the anvil shall be wiped dry and
free of oil. The copper cylinder shall be put in place and centered between the
head of the piston and the bottom of the anvil. The anvil shall be screwed down
lightly on the cylinder, using the thumb and forefinger, but not under stress.
The dummy cartridge shall then be removed from the chamber.
2.7.3.6 In order that the propellant shall be uniformly positioned from car-
tridge to cartridge before firing, attention to detail is necessary in handling
and chambering the cartridge. The cartridge shall first be held vertically, bul-
let upward, and then rotated slowly, end over end in a vertical plane, stopping
the rotation momentarily after 180 of rotation when the bullet is downward, and
then continuing through the remainder of 360, stopping with the cartridge again
bullet-end upward. The bullet-end of the cartridge should now be lowered slowly
to a position slightly above horizontal. The cartridge shall be' chambered very
carefully, taking care that the primer-end of the case is not elevated above the
bullet -end. (The object is to have the cartridge seated in the chamber ready to
fire, with the propellant in a loose condition at the primer end of the case.)
2.7.3.7 The breech-block shall be closed gently. If the technician encounters
any difficulty closing the breech-block or engaging the trip lever, the test shall
be discontinued until such difficulty is corrected. If any delay should occur
after the cartridge is placed in the chamber and the duration of _the delay is such
that the temperature of the cartridge has changed significantly, that cartridge
shall be extracted and removed from the test and another inserted in its place.
2738 The technician makes a final check to assure that the anvil is
screwed to a snug position on the copper cylinder. Care is taken to see that the
copper cylinder is not compressed by the anvil prior to firing. The proper torque
to be applied to the thumb-screw is about one pound-inch. (This torque can be
estimated with satisfactory accuracy by an experienced technician; to familiarize
inexperienced technicians with the desired degree of tightness, a torque-measuring
device may be employed. This can be accomplished by drilling and tapping (threading)
an axial hole in the knurled head of the anvil (thumb-screw) and Inserting a bolt
or screw to which a torque-measuring wrench can be attached. The usefulness of
the anvil (thumb-screw) is not impaired by this modification,)

2.7.3.9 The trip lever, to which the lanyard Is attached, shall be engaged
gently with the hammer. The technician' retires to a safe position and pulls the
lanyard with a smooth firm motion. The velocity of the shot shall be recorded
by the chronographer.
2.7.3.10 The breech-block shall be opened, the fired case extracted and
visually examined by the technician for possible case casualties. The copper
cylinder shall be removed and placed in the recessed holding block. The piston
shall be removed from the piston hole. The knockout tool is then used to force
the obturating cup from the piston hole into the chamber. The obturating cup
is then removed from the chamber either by air or a cleaning rod with cleaning
patch attached. The procedure prescribed in 2.7.3.^ shall be repeated. Upon
removal of the dummy cartridge, the chamber and bore shall be checked for the
possibility of any obstruction remaining in the barrel.
2.7.3.11 The procedure prescribed in 2.7.3.5 through 2,7.3.10 shall be
repeated until twenty cartridges have been fired.
2.7.3.12 The copper pressure cylinders whose identities are maintained
throughout the test are measured in the same manner as they were prior to the
test. The difference in length (set in inches) Is then applied to the proper
tarage table, the corresponding PSI obtained and recorded on the report form.
2.7.3.13 If the technician observes any abnormality tending to invalidate
either the velocity or pressure measurement, it is the technician's responsibility
to notify the chronographer immediately. The record of any such shot is noted on
the test sheet and then reported to the supervisor. If the technician reports
nothing abnormal, yet the recorded velocity appears questionable, the chronographer
questions the shot before continuing the test and takes such action as supervision
may prescribe.

assessment, obtains poor uniformity within the tests or poor reproducibility be-
tween the tests, that proof test facility is requested to repeat the tests, and
if necessary, is given, specialized assistance in an effort to determine the causes
thereof.
2.7.5.18 Upon completion of the simulated assessment tests, duplicate copies
of the individual ballistic sheets as well as duplicate copies of a summary table
of average results shall be forwarded to the installation responsible for publish-
ing the assessment values, where a complete study of the data shall be made.

ment values 1 , and the general agreement between ranges is acceptable, the assess-
ment becomes, official and is published immediately.
2.7.3...20 Should the majority of participating proof test facilities be not
in close agreement with the proposed assessment, the assessment and simulated
assessment shall be refired. Retests of all tests will be evaluated by the in-
stallation responsible for publishing the assessment values, and no official pro-
nouncement made until the differences are reconciled.

ACCURACY TEST PROCEDURE
3.1 PURPOSE
The Accuracy Test is fired under controlled conditions at a target
located at a specified distance from the weapon to determine the uniformity and
dispersion of bullets. In order to minimize weapon inaccuracies, the test shall
be fired in a rigidly mounted teat weapon.
3.2 EQUIPMENT
3.2.1 Equipment listed in the Accuracy section of the appropriate
Inspection Equipment List shall be used.
3.2.2 The target size for Accuracy Tests shall not be less than 24-" x 24".
3.2.3 The pier or mount on which the test assembly is mounted shall be of
solid const ructlpn.
TEST PROCEDURE
3.3.1 Pre-flring (Preparation for test)
3.3.1.1 The accuracy test weapon is assembled and locked in position on the
mount and boreelghted into position. It is of prime importance that the assembly
be mounted properly so that the weapon maintains its original position from shot to
shot.
3.3.1.2 The following measurements shall be made before a test weapon Is
placed in service, after misfires, pierced primers or f-lowbaclcs ; or whenever a
par.t replacement has been made in the assembly:
Limit s

AMCR 715-505
Volume 5
3.3.2 During Firing
3.3.2.1 A sufficient number of unrecorded cartridges of the type of ammu-
nition under test shall be fired to assure that the test weapon is correctly
'Sighted on the target, but in any event a minimum of three (3) cartridges shall
be fired to warm and foul the weapon when it is first put into service and after
it has been cleaned or cooled. The technician observes the location of jhe shots
on the target so that the alignment of the weapon may be adjusted, if necessary.
3.3.2.2 After the warming (fouling) cartridges have been fired the target
shall be changed so as to present a fresh surface for the succeeding target.
Thereafter, the target shall be changed after each target of ten cartridges has
been fired;
3.3.2.3 Consideration Is not given to the position of the propellarit in the
cartridge case, except that the manner of handling the ammunition from cartridge
to cartridge is reasonably uniform. Ten (10) cartridges shall then be fired in
even sequence at a rhythmic uniform rate, as rapidly as .service >of the weapon per-
mits. When firing tracer ammunition, the rate of fire Is reduced to permit ob-
servations of trace for each individual cartridge.
3.3.2.U The approximate location of the center of impact and the estimated
size (Extreme Vertical and Extreme Horizontal) of the target first fired .shall be
observed by the technician in order that alignment of the weapon may be .adjusted,
if necessary,
3.3.2.5 The procedure prescribed in 3.3.2,3 and 3.3,2.4 shall then be
repeated until the specified number of targets have been fired in the first weapon,
five (5) targets max., or when the exposed metal surface of the test barrel be-
comes too hot to grasp with the bare hands (approx. 1HOF. ) , at which time the
barrel shall be cooled to ambient temperature before the test is continued.
3.3.2.6 After the required number of targets has been fired with the first
weapon, that weapon shall be removed from the mount and cooled to ambient tem-
perature.
3.3.2.7 The second test weapon shall then be assembled on the mount and the
procedure prescribed in 3.3.2.1 thru 3.3.2.6 is repeated. If a third test weapon
"be used, the same procedure shall be repeated.
3.3.2.8 If it is necessary to use a weapon, after it has been cooled, the
chamber and bore shall be cleaned before any additional firing, and three warming:
(fouling) cartridges shall then be fired.

FUNCTION AND CASUALTY TEST PROCEDURE
5 . 1 PURPOSE
To determine if the ammunition can be expected to perform satisfactorily
In the service weapons for which it has been designed under conditions of field
usage. Ammunition may be balllstically satisfactory, i.e., it may comply with
individual performance specifications such as velocity, pressure, trace, etc., yet
be unfit for use in the field because of undesirable characteristics which jeop-
ardize the safety of personnel.
Casualties and malfunctions can be caused either by the ammunition or
by the weapon in which it is fired, so that, to a certain extent, these two fac-
tors are interdependent. A faulty weapon or a poorly adjusted weapon can cause
casualties in normal ammunition, but if the weapon be in proper condition when
casualties are encountered, then the fault lies with the ammunition.
5.2 EQUIPMENT
5.2.1 Equipment listed in the Function and Casualty section of the
appropriate Inspection Equipment List shall be used.
5.2.2 Weapons shall conform to the dimensions shown on the applicable draw-
Ings.
5.3 TEST PROCEDURE
5.3.1 Pre-firing (Preparation for test)
5.3.1.1 Weapons shall be of the latest design or most recent issue. Re-
ceivers for submachine-guns shall be discarded when any of the following occurs:
(a) 25,000 cartridges have been fired; (b) sufficient wear occurs in non-replace-
able receiver components to prevent, proper functioning; (c) any unusual behavior
proven attributable to the recelveir. A pistol shall be retired from further use,
regardless of apparent . condition, after it has fired 10,000 cartridges.
5.3.1.2 Weapons employed in this test must have barrels in serviceable
condition. To assure this, all barrels -shall be Inspected visually before use
and rejected if any defect is discovered. A barrel shall be retired from further
use, regardless of apparent condition, after it has fired 10,000 cartridges. Un-
usual behavior, proven to be attributable to the barrel, may also be reason for
discarding of the barrel.

5.5 OPERATIONAL NOTES
5-5.1 In the event any stoppage occurs during firing of the test, a detailed
check shall be made to determine whether the ammunition or the weapon is at
fault. If the stoppage was caused by a misfire, the check of the weapon shall In-
clude measurement of the firing-pin protrusion, firing-pin indent and headspace,
To assist in determining whether ammunition or weapon is responsible for a
stoppage, it is good practice to test the weapon in question using ammunition of
known characteristics, and to test the ammunition in question toy firing in
another weapon of the same type, If it is established that some faulty condi-
tion of the weapon is responsible for the stoppage, the test shall be disregarded,
the weapon shall be corrected or replaced, and the tests with that type weapon
shall be refired.
5.5.2 If a misfire is encountered, irrespective of the type of test wherein
it occurs, .the weapon is examined carefully to determine if the cause is attribut-
able to the gun. In any ballistic acceptance test where a misfire occurs, a
second attempt to fire a primer shall not be made. It is mandatory that a period
of at least five (5) mlnutea elapse after the misfire occurs before the action of
the weapon is opened, .whereupon the misfired cartridge is carefully removed In
accordance with existing safety regulations, and preserved for further examination.
All handling and examinations of mlsfjLred cartridges shall be conducted with due re-
gard for the hazards involved. The weapon In which a misfire occurs shall be
thoroughly checked; it shall be disassembled and all component parts critically
scrutinized. Results, of such examination shall be included on the test report as
a matter of Information.
.5.5.2.1 Laboratory examination of the misfired cartridges shall be made to
determine the specific cause, the result of the investigation Is included on the
test report.
5.5.3 Upon completion of firing, all cartridge cases from the test ammunition
shall be carefully examined for firing defects. If any defect is found, a detailed
check of the weapon shall be made to determine whether the ammunition or the
weapon is at fault. If it is established that a faulty weapon is responsible
for the firing defect, then the test shall be disregarded, the weapon shall be
corrected or replaced, and the tests with that type weapon shall be refired. If
it cannot be established that the weapon or other equipment is at fault, then the
firing defects shall be charged against the ammunition.

b. A crack is a surface condition and represents a separation of the
metal partially through the wall. Cracks are not considered to be
splits,
A suggested method for determining cracks and splits follows:
Splits in the cartridge case, after the Mercurous Nitrate test are
detected by filling the case with water (water temperature 70 F. to 100 P.) to
the mouth until a convex meniscus condition exists and placing the thumb of
the hand over the mouth of the case. If the case Is split,, this exerts suffi-
cient pressure to force the water through the opening.
Splits in the assembled cartridge are not so easily detected unless the
split Is at the mouth of the case and the bullet metal is seen through the split
If the split Is in the body, the only way to determine whether It Is a split or
crack is to disassemble and follow the procedure used for the case check,

VELOCITY, CHAMBER-PRESSURE TEST PROCEDURE
8.1 PURPOSE
The Velocity and Chamber Pressure tests are fired simultaneously and
Is a precisely controlled test to:
a. Ascertain the velocity uniformity and level of the ammunition lot
under test.
b. Determine the chamber pressure exerted, expressed in pounds per
square Inch, in the chamber of the gun. This test Is performed
as a safety measure to Insure that the pressure developed by the
ammunition is safe for firing In the weapons for which it is In-
tended.
8.2 EQUIPMENT
8.2.1 Equipment listed in the Velocity, Chamber -Pressure section of the
appropriate Inspection Equipment List snail be used.
8.2.2 The firing range shall be arranged as shown on Chart #1, at the end
of this section.
8.2.3 Pier or mount of solid construction on which test fixture assembly
shall be mounted.
8.3 USE OP REFERENCE CARTRIDGES
8.3.1 Reference cartridges shall be used to establish range and equipment
corrections prior to firing an ammunition lot for acceptance. One reference car-
tridge shall be fired for each cartridge of the test sample to be fired, up to
twenty (20) cartridges. When the test consists of more than twenty (20), but not
more than forty (40) cartridges, then twenty (20) reference cartridges shall be
fired. When the test consists of more than forty [40) cartridges, one reference
cartridge shall be fired for every two (2) test cartridges.
8.3.2 After the required number of reference cartridges has been fired, the
actual average velocity and chamber pressure of the reference cartridges shall be
compared with the assessed values. If the assessed value is higher than the
actual average velocity or chamber pressure, the difference Is a plus correction
and shall be added to the average velocity or chamber pressure of the test car-
tridges. If the assessed, value is lower than the actual average velocity or cham-

ber pressure, the difference Is a minus correction and shall be subtracted from
the average velocity or chamber pressure of the test cartridges. If the assessed
value and the actual average velocity or chamber pressure are identical, then no
correction Is applied.

poses, of. fehe results from each barrel in which reference cartridges are fired
oiltalned sha11 be Compared with the previous ones to determine
whether the test conditions remain stable to a certain degree.
8.4 MEASUREMENT OF COPPER PRESSURE CYLINDERS
8.4.1 The chamber-pressure shall be determined by using the radial copper
pressure cylinders. One cylinder shall be used for each cartridge fired.
8.4.1.1 The copper pressure cylinders shall be measured individually usine
a properly calibrated micrometer graduated from 0.0001 inch. The cylinders shall
be measured prior to firing, measurements recorded and the cylinders placed in

again, and the decrease in length obtained by subtraction of the actual readings
The decrease in length obtained for each cylinder shall then be applied to the
appropriate tarage table (a tarage. table is supplied with each box of copper
pressure cylinders) and the corresponding chamber pressure (PSI) shall be re-
corded in such a manner that the velocity of each cartridge can be identified
with the corresponding chamber pressure obtained.

volving the use of different tarage tables, they shall be .tested in comparison
with the cylinders being replaced T>y firing forty (40) reference cartridges for
chamber pressure in a barrel assembly of known characteristics, using twenty (20)
of the new cylinders in alternation, with twenty (20) of the old cylinders The

8.5 TEST PROCEDURE
8.5.1 Pre-firing (Preparation for test)
8.5.1.1 The required number of test cartridges shall be placed in a vertical
position, primer-end down, in a recessed holding block. The test cartridges shall
be permitted to come to a temperature of 6oF. to 8oF. prior to being placed in
the temperature-controlled container or room. The recessed holding block con-
taining the test cartridges shall be placed In a temperature-controlled container
or room In such a manner that all cartridges are subjected to a uniform tempera-
ture for a minimum of two hours, prior to firing. The container or room shall be
maintained at a temperature of 70P. , + 2P. , with a relative humidity of 60 per-
cent + 5 percent, and be of sufficient capacity to allow free circulation of air.
8.5.1.2 The required number of reference cartridges are then handloaded.
8.5.1.3 The barrel assembly Is assembled In the test fixture on the mount,
The chamber and bore of the barrel are wiped' dry. The barrel Is then boresighted
into position,
8.5.1.4 The barrel assembly shall be In accordance with the applicable
drawings, if the "no-go" gages enter either the upper or lower end of the piston
hole, the barrel assembly shall be disqualified.
8.5.1.5 The following -measurements shall be made before a barrel assembly
Is placed In service, after misfires, pierced primers, flowbacks, or whenever a
part replacement has been made in the bolt assembly.
Limit s
Firing-pin indent .011" - .015"
Firing-pin protrusion .060" - .068"
Headspace .898" - .903"
8.5.1.6 Lumillne screens are checked for position. It is of the utmost
importance that the lumiline screens be placed In their proper positions, meas-
urements must be accurate within 1/4", Distance between screens shall be 25 feet.
8.5.1.7 The required number of copper pressure cylinders are measured as
prescribed in 8,4.1.1.
8.5.1.8 The recessed holding block containing the individually measured copper
pressure cylinders, a sufficient quantity ofobturators (a new obturator shall be
used for each cartridge to be fired) and the pressure piston should be placed at a
point convenient to the technician.
Chapter 1
8-3
During Firing
3.5.2.1 Five warming (fouling) shots shall be fired. To fire the warming
(fouling) shots, it shall be necessary to service the chamber pressure assembly
\ilsh an obturating cup, the pressure piston, and a copper pressure cylinder. The
same cylinder and obturating cup may be used when all the warming shots are being
fired, the anvil being screwed down on the cylinder following each shot. Velocity
readings should be recorded by the chronographer to assure that the velocity-measuring
..-..rilpment is functioning properly,
8.5.2.2 The recessed holding block containing the reference cartridges is
removed from the controlled temperature room or container and placed at. a point
convenient to the technician, provided the temperature of the firing room Is 70F,,
+ 5F., otherwise the cartridges shall be placed in an insulated box which has been
conditioned at 70F. , + 5F. , and the box placed at a point convenient to the
technician; the cartridges are then removed singly from the insulated box Immediately
teiore firing. If an insulated box is not -available., then the- oart nidges shall be
removed singly from the controlled-temperature room or container Immediately before
firing. The controlled -temperature room or container shall be maintained at 70P, ,
+ 2 F., and a relative humidity of 60 percent, + 5 percent.
8.5.2.3 The dummy cartridge shall be placed in the chamber of the barrel
assembly. The obturating cup shall be placed in the piston hole, mouth-end down,
and partially seated using the stem of the knockout tool. The shank of the pressure
piston shall be dipped In oil and the oil then be allowed to drain from the piston,
The drop of oil adhering to the bottom of the piston shank shall then be removed by
Uniehing the bottom of the piston shank to a cleaning patch. The piston shall then
be Inserted into the piston hole and pressed down on the obturating cup until the
pisi;on has reached its correct final position. The head of the piston and the bottom
or the anvil shall be wiped dry and free of oil. The copper cylinder shall be put .in
place and centered between the head of the piston and the bottom of 'the anvil 1. The
anvil shall be screwed down lightly on the cylinder, using the thumb and forefinger
but noc under stress. The dummy cartridge shall then be removed from the chamber. '
' hamber and core are examined for possible obstruction.
5 ' 2 ;^ In . order that fche Propellant shall be uniformly positioned from

care that the primer-end of the case is not elevated above the bullet-end. (The
object is to have the cartridge seated in the chamber ready to fire, with the pro-
pellant in a loose condition at the primer end of the case.)
8.5.2.5 The breech-block shall "be closed gently. If the technician en-
counters any difficulty closing the breech-block or engaging the trip lever, the
test shall be discontinued until such difficulty Is corrected. If any delay
should occur after the cartridge is placed in the chamber and the duration of the
delay is such that the temperature of the cartridge has changed significantly
(30 seconds or longer) that cartridge shall be extracted and another Inserted In
its place.
8.5.2.6 The technician makes a final check to assure that the anvil is
screwed to a snug position on the copper cylinder. Care Is taken to see that the
copper cylinder is not compressed by the anvil prior to firing. The proper torque
to be applied to the thumb -screw Is about one pound-Inch, (This torque can be
estimated with satisfactory accuracy by an experienced technician; fco familiarize
inexperienced technicians with the desired degree of tightness, a torque -measuring
device may be employed. This can be accomplished by drilling and tapping (threading
an axial hole in the knurled head of the anvil (thumb-screw) and inserting a bolt
or screw to which a torque-measuring wrench can be attached. The usefulness of the
anvil (thumb-screw) Is not impaired by this modification.)
8.5.2.7 The trip lever, to which the lanyard is attached, shall be engaged
gently to the hammer. The technician retires to a safe position and pulls the
lanyard with a smooth firm motion. The velocity of the shot shall be recorded by
the chronographer.
8.5.2.8 The breech-block shall be opened, the fired case extracted and visuall
examined by the technician for possible case casualties. The copper cylinder shall
be removed and placed in the recessed holding block. The piston shall be removed
from the piston hole. The knockout tool is then used to force the. obturating cup
from the piston hole into the chamber. The obturating cup is then removed from the
chamber using a cleaning rod with a dry cleaning patch attached.
8.5.H.9 The procedure prescribed In 8.5,2.3 through 8.5,2.8 shall be re-
peated until the required number of reference cartridges has been fired,
8.5.2.10 The velocity correction shall then be obtained as prescribed in 8,5,2
8.5.2.11 The copper pressure cylinders whose Identities are maintained through
out the test are measured in the same manner as they were prior to the test. The
difference in length (set" in Inches) is then applied to the proper tarage table,
and the corresponding PSI is obtained and recorded. The chamber pressure cor-
rection shall then be obtained as prescribed In 8,3.2.

SECTION 1
FUNCTION AND CASUALTY TEST PROCEDURE
1.1 PURPOSE
To determine, by firing In weapons of representative types, whether
or not the ammunition undergoing acceptance can be expected to perform satis-
factorily, under conditions of field usage, in the service weapons for which
it has been designed,
Casualties and malfunctions can be caused either by the ammunition
or by the weapon in which it is fired, so that, to a certain extent, these two
factors are interdependent. A faulty weapon or a poorly adjusted weapon can
cause casualties in normal ammunition, but If the weapon be in proper condition
when casualties are encountered, then the fault lies with the ammunition.
1.2 EQUIPMENT
1.2.1 Equipment listed In the Function and Casualty section of the
appropriate Inspection Equipment List if or Blank Cartridges shall be used,
1.2.2 Weapons shall conform to the dimensions shown on the applicable
drawings ,
1.3 TEST PROCEDURE
1.3..1 Pre-flring (Preparation for test)
1.3.1.1 Weapons shall be of the latest design or most recent 'issue. Pis-
tols shall be retired from further use, regardless of apparent condition, after
it has fired 10,000 cartridges.
1.3.1.2 The test weapon(s) shall be fired rapid fire, either by hand or
in an applicable fixed rest.
1.3.1.3 The test cartridges shall be examined for obvious defects before
being loaded into the applicable magazines. If visual defects are found, the
defective cartridge(s) shall be replaced and the defects shall be noted on the
test sheet form,
1,3.2 During Firing
1.3.2.1 The pistol(s) shall be cooled after TO cartridges (ten magazines)
have been fired.
Chapter 2
1-1
AMCR- 715-505
Volume 5
1.3.2.2 The number of pistols and the quantity of cartridges to be
fired -in each weapon shall be as specified in the applicable specification.
The procedure for firing each of the weapons specified shall be the same in-
sofar as possible. The magazine shall be Inserted into the weapon and the
cartridges fired as rapidly as the action of the weapon permits. The magazine
Is then removed and another inserted. A time interval of not more than one-half
minute shall be allowed between magazines. After firing ten magazines (70
cartridges) maximum, the weapon shall be permitted to cool to ambient tempera-
ture.
1.3.2.3 Fired cases shall be visually examined by the technician for
possible case casualties.
1.4 RECORDING OF DATA.
1.4.1 Casualties shall be reported In accordance with terminology of
1.6 and the applicable specification,
1.4.2 Misfires shall be recorded and the cause determined and described.
1.4.3 The function and casualty test requires careful attention and alert-
ness, and any unusual occurence in gun function or appearance of fired cases
shall "be noted.
1.4.4 Failures of gun parts shall be shown on the ammunition report.
1.5 OPERATIONAL NOTES
1.5-1 In 'the event any stoppage occurs during firing of the test, a de-
tailed check shall be made to determine whether the ammunition or the weapon
is at fault. If the stoppage was caused by a misfire, the check of the weapon
shall include measurement of the firing-pin protrusion and firing-pin indent.
To assist in determining whether ammunition or weapon is responsible for a
stoppage, it is good practice to test the weapon in question using ammunition
of known characteristics, and to- test the ammunition in 'question by firing in
another weapon of the same type. If it is established that some faulty con-
dition of the weapon is responsible for the stoppage, then the test shall be
disregarded, the weapon shall be corrected or replaced and the tests re-fired.
1,5.2 If a :,:isfire is encountered, irrespective of the type of test where-
in it occurs, the weapon is examined carefully to determine if the cause Is
attributable to the gun. In any ballistic acceptance test where a misfire
occurs, a second attempt to fire a primer is not made. It Is mandate^ that a
period of at least five (5) minutes elapse after the misfire occurs before the
action of the weapon is opened, whereupon the misfired cartridge is carefully
Chapter 2
1-2
AMCR 715-505
Volume 5
removed in accordance with existing safety regulations, and preserved for
further examination. All handling and examinations of misfired cartridges
shall be conducted with due regard for the hazards involved. The weapon in
which a misfire occurs shall be thoroughly checked; i.e., it shall be disassembled
and all component parts critically scrutinized. Results of such examinations
shall be included on the test report as a matter of information.
1.5.2.1 Laboratory examination of the misfired cartridge(s) shall be made
to determine the specific cause and the results of the investigation included
on the test report.
1.5.3 Upon completion of firing, all cartridge cases from the test ammuni-
tion shall be carefully examined for firing defects. If any defect is found a
detailed check of the weapon shall be made to determine whether the ammuni-
tion or the weapon is at fault. If It is established that a faulty weapon
is responsible for the firing defect, then the test shall be disregarded, the
weapon shall be corrected or replaced, and the tests with that type weapon shall
be reflred. If it cannot be established that the weapon is at fault, then the
firing defects shall be charged against the ammunition.
1 . 6 DEFINITIONS
1.6.1 Misfire.- Failure of a round of ammunition to fire after the initi-
ating blow has been applied to the primer. There are two general categories
of misfires :
a. The primer fails to fire when struck by the firing-pin.
b. The propellant does not ignite when the primer fires normally.
1.6.2 Perforated Primer.- One in which the primer cup Is entirely per-
forated by the firing pin. It can be identified by a visible hole through the
primer, or, if the perforation be minute, by discoloration of the firing pin
indent caused by burning gas.
1.6.5 Primer Leak,- Discoloration caused by gas leakage around the junc-
tion between the primer cup and the primer pocket wall,
1.6.U Loose Primer.- Looseness, but not so as to permit the fired primer to
fall from the primer pocket after the cartridge is fired.
165 Blown Primer, or a Primer which falls out of the primer pocket.- A
blown primer is a primer which, when the cartridge is fired, is separated com^
pletely from the head of the cartridge' case, and both the head of the case and
Chapter 2
1-3
AHCR 715-505
Volume 5
pocket are enlarged and deformed. A primer which falls out of the primer pocket
is In the same category as a blown primer tut the distortion to the primer pocket
is less obvious,
1.6.6 Ruptured Case.- A circumferential separation of the case wall pro-
duced by firing. Ruptures are divided into two categories, partial and complete.
A partial rupture is one which extends less than 360 around the case; a complete
rupture Is one which extends entirely around the case, separating the case into
two parts. Ruptures are designated according to position, as indicated on
Drawing 0764367^.
1.6.7 Split Case,- A longitudinal separation of the metal In the case wall
produced by firing. Splits shall be classified as prescribed by the cartridge
specification and Drawing 076^3674,
1.6.8 Failure to Extract.- The fired case is not removed from the weapon
chamber by normal gun action.

3,3.1.6 The flight of the rod Is affected to a degree by the direction
and velocity of the wind over the outdoor range. Therefore, range tests should
not be fired when the velocity of the wind is greater than ten (10) miles per
hour, or varying by more than five (5) miles per hour.
3.3.2 During Firing
3.3.2.1 A sufficient number of unrecorded cartridges of the type of ammu-
nition' under test shall be fired to assure that the test equipment is function-
ing properly. It Is not necessary to attach the line to the rods when firing
these cartridges. The approximate location of the shots fired are reported to the
technician In order that alignment of the weapon may be adjusted if necessary.
3.3.2.2 The recessed holding block containing the test cartridges is re-
moved from the controlled temperature container or room and placed at a point
convenient to the technician, provided the temperature of the firing room or
firing position is 70F t> + 5F. , otherwise, the cartridges shall be placed in
an insulated box (-three cartridges at a time) which has been conditioned at
70F. , + 5P;j and the box placed at a point convenient to the technician. If
an Insulated box is not available, then the cartridges shall be removed singly
from the controlled temperature container or room and fired. The controlled-
temperature container or room shall be maintained at 70 F. , + 2 F., and a rela-
tive humidity of 60 percent, + 5 percent,
3.3.2.3 Because the weapon is a break -open type, It will be necessary to
remove the weapon from the rest each time a cartridge Is to be chambered.
3.3.2.H The weapon Is removed from the rest and broke open. The fired
case is removed from the chamber. Although it is not necessary to rotate the
cartridge 360 before chambering, the cartridge shall be chambered very care-
fully. The weapon is then made ready for firing and placed In the rest in firing
position.
3.3.2.5 The line-carrying rod, with line attached, is carefully inserted
Into the barrel from the muzzle end, and gently seated against the mouth of the
chambered cartridge. Extreme caution must be taken when performing this opera-
tion so that the technician does not place himself in front of the muzzle of the
weapon. The line shall be on a spool which is attached to the rest, directly
under the muzzle of the weapon,
i
3.3.2.6 If any delay should occur after the cartridge is placed in the
chamber and the duration of the delay is approximately 30 seconds or longer,
that cartridge shall be extracted and another inserted in Its place.

VELOCITY AND CHAMBER PRESSURE TEST PROCEDURE
(LINE -THROWING- CARTRIDGE)
5 . 1 PURPOSE
5.1.1 The Velocity and Chamber Pressure tests are fired simultaneously and
are precisely controlled tests to:
a Determine the pressure exerted, expressed in pounds per square
inch in the chamber of a gun. The test is performed as a safety measure to insure
that 'the pressure developed by the ammunition is safe for firing in the weapons
for which It is Intended.
b. Ascertain that the velocity value obtained with the cartridge does
not exceed the requirement of the specification.
5.2 EQUIPMENT
5 2 1 Equipment -listed in the Velocity-Chamber Pressure section of the
appropriate Inspection Equipment List shall be used.
522 The firing range shall be arranged as shown on Chart #2, at the end of
this section. The maximum distance between the lumiline screens shall be ten (3D)
feet.
5.2.5 A pier or mount of solid construction, on which the test fixture assem-
bly shall be mounted, is required.

and the corresponding chamber pressure (PSI) shall be recorded In such a manner
that the velocity of each cartridge can tie identified with the corresponding
chamber-pressure obtained.
5.4 TEST PROCEDURE
5.4.1 Pre-firing (Preparation for test)
5.^.1,1 The required number of test cartridges shall be drilled in a press
using a. drill Jig to assure that the hole Is drilled in the specified position.
A #4y drill (.0785 inch dia.) shall be used. The drill press shall be so arranged
that it can be operated and observed from a protected area.
5.4.1.2 After drilling, the test cartridges shall be placed in a vertical
position primer-end down, in a recessed holding block. Temperature of the test
cartridges 'shall, be 6oF. to 8oP. prior to being placed in the temperature con-
trolled container or room. The recessed holding block containing the test car-
tridges shall be placed in a temperature controlled container or room in such a
manner that all cartridges are subjected to a uniform temperature for a minimum of
two hours, prior to firing. The container or room shall be maintained at a tempera-
ture of 70 P (I i 2 P., and a relative humidity of 60, 5 percent, and be of suffi-
cient capacity to allow free circulation of air around the cartridges,
5.4.1.3 The velocity-chamber pressure barrel assembly is assembled in the
test fixture, on the mount. The chamber and bore of the barrel are wiped dry. The
barrel is then boresighted into position,
5.4.1.J+ The velocity -chamber pressure barrel assembly shall be In accordance
with the applicable drawings. When the diameter of the piston hole exceeds the wear
limit permitted (.2066) at any point along the surface of the hole, the barrel
assembly shall be disqualified.
5.4,1.5 Lumlllne screens are checked for position. It is of the upmost im-
portance that the lumiline screens be placed in their proper positions, measure-
ments must be accurate. The lumiline screen nearest the muzzle of the weapon shall
be of blast -proof construction. The range shall be equipped with a suitable recovery
container filled with cotton waste, or equivalent, for stopping and preserving a
propelled line-carrying rod, so that recovery can be made. The recovery container
should be located at approximately fifteen (15) feet from the muzzle of the
velocity-chamber pressure test weapon, in the line of fire.
5.4.2 During Firing
5. 4. H.I When the test is being conducted, the chamber of the weapon shall be
empty and the bolt in the open position at all times, until ready to fire. This
precaution is necessary because the technician Is required to place himself between
Chapter 2
5-2
AMCR 715-505
Volume 5
the muzzle of the weapon and the recovery container during certain operations
(See 5.1.2.11).
5.4.2.2 The line-carrying rod(s) is/are placed at a point convenient to the
technician! Three warming (fouling) shots having components of the same type as
the test cartridges are fired and velocity readings of the line-carrying rods are
recorded by the chronographer to assure that the equipment is functioning properly.
To fire the warming (fouling) shots, it shall be necessary to service the velocity-
chamber pressure assembly with an obturating cup, the pressure piston, and a copper
pressure cylinder. The same cylinder and obturating cup may be used when all the
warming shots are being fired. The anvil is screwed down on the cylinder following
each shot.
5.4.2.3 The recessed holding block containing the test cartridges (reference
cartridges are not fired) is removed from the controlled temperature room or box
and placed at a point convenient to the technician, provided the temperature of
the firing room is 70F., + 5F. , otherwise the test cartridges shall be placed in
an insulated box which has been conditioned at 70 P., 5F. , and the box placed
at a point convenient to the technician. Cartridges are then removed singly from
the Insulated box and fired. If an Insulated box is not available then the car-
tridges shall be removed singly from the controlled temperature room or container
and fired.
5M-231 When firing cartridges which have "been conditioned at either high
or low'temperature, the cartridges shall be placed in an insulated box which has
also been conditioned at the specified temperature. No more than three - car, ridged
shall be placed in the insulated box, at any one time. The insulated box containing
the cartridges is then placed at a point convenient to the technician; the cartridges
removed singly from the insulated box and fired. If an Insulated box is not avail-
able, then the cartridges shall be removed singly from the controlled temperature
box or room and fired.
5 4 2 4 A dummy cartridge(unprimed, mouth crimped cartridge case) shall be
placed in the chamber of the barrel assembly. The obturating cup shall be Placed
in the piston hole, mouth-end down, and partially seated using the stem of the
knockout tool. The shank of the pressure piston shall be dipped in oil and _ the oil
then be allowed to drain from the piston. The drop of oil adhering to the bottom
of the piston shank shall then be removed by touching the bottom of the piston snank
to a cleaning patch. The piston shall then be inserted into the piston hole and
pressed down on the obturating cup until the piston has reached its correct final
position. The head of the piston and bottom of the anvil shall be 'wiped dry and
free of oil. The copper cylinder shall be put in place and centered between the
head of the piston and the bottom of the anvil. The anvil shall be screwed down
lightly on the cylinder, using the thumb and forefinger, but not under stress.
Chapter. 2
5-3
5.4.2.5 The line-carrying rod, without line attached, is carefully placed
in the muzzle of the test weapon and gently seated against the mouth of the cham-
bered dummy cartridge. The dummy cartridge shall then be removed from the chamber.
5.4.2.6 Since the cartridges are assembled so that the wad is seated directly
on the propellant, eliminating air-space, it is not necessary to rotate the car-
tridge through 360 prior to chambering. However, the cartridges shall be handled
uniformly and carefully when they are being chambered. During chambering, the
drilled hole in the cartridge case must be properly aligned with the piston hole
in the barrel assembly.
5.4.2.7 The breech-block shall be closed gently. If the technician encoun-
ters any difficulty closing the breech-block or engaging the trip lever, the test
shall be discontinued until such difficulty is corrected. If any delay should
occur after the cartridge is placed in the chamber and the duration of the delay
is such that the temperature of the cartridge has changed significantly, that
cartridge shall be extracted and another inserted in its place.
5.4.2.8 The technician shall make final check to assure that the anvil is
screwed to a snug position on the copper cylinder. Care is taken to see that the
copper cylinder is not compressed by the anvil prior to firing. The proper torque
to be applied to the thumb-screw is about one pound-inch. (This torque can be
estimated with satisfactory accuracy by an experienced technician; to familiarize
inexperienced technicians with the desired degree of tightness, a torque-measur-
ing device may be employed. This can be accomplished by drilling and tapping
(threading) an axial hole in the knurled head of the anvil (thumb -screw) and in-
serting a bolt or screw to which a torque -measuring wrench can be attached. The
usefulness of the anvil (thumb-screw) is not impaired by this modification.)
5.4.2.9 The trip lever, to which the lanyard is attached, shall be engaged
gently with the hammer. The technician retires to a safe position and pulls the
lanyard with a smooth firm motion. The velocity of the shot shall be recorded
by the chronographer.
5.4.2.10 The breech-block shall be opened, the fired case extracted and vis-
ually examined by the technician for possible case casualties. The copper cylinder
shall be removed and placed in the recessed holding block. The piston shall be
removed from the piston hole. The knockout tool is then used to force the obtura-
ting cup from the piston hole into the chamber. The obturating cup is then re-
moved from the chamber either by air or a cleaning rod with a cleaning patch attached
5.4.2.11 The technician then recovers the fired line-carrying rod from the
recovery container and examines it carefully. If the rod is not damaged in any
way It shall be used again. Should the rod be damaged in any way, it shall be
replaced with a new rod.

PRIMER SENSITIVm TEST PROCEDURE
1 . 1 PURPOSE
To determine the sensitivity limit s' within which the primer functions
in order to provide assurance that :
a. The primer will be safe to handle.
b. The primer will fire in the cartridge case and weapon(a) for
which it is Intended.
1.2 EQUIPMENT
1.2,1 Equipment listed in Primer Sensitivity section of the appropriate
Inspection Equipment List shall be used.
1.3 TEST PROCEDURE {Complete Run-down teat)
1-3.1 Preparation for test
1.3.1.1 This test shall tae conducted on empty primed cases. In the event
the primed cases must be obtained by disassembly of cartridges, the disassembly
shall be accomplished in such a manner as to cause the least possible distor-
tion of the cartridge case.
1.3.1.2 The machine shall have a firing -pin protrusion of, .058 Inches mini-
mum. This shall be measured by seating the firing pin fully against the shoulder
stop in the firing-pin retainer, and measuring the resulting protrusion of the
point of the firing pin from the face of the flrlng-pln retainer. A micrometer,
dial Indicator, or other suitable measuring instrument shall be used for this
purpose. If the firing-pin protrusion is found to be less 'than the specified
dimension, then the firing pin or the firing-pin retainer shall be replaced as
necessary to achieve the required firing-pin protrusion.
1.3.1.3 A headspace gage having a dimension of 0.893 inches shall be placed
in the case holder. The case holder shall be lowered, If necessary, until the
breech-block closes and clamps freely without interference with the headspace
gage. The case holder shall then be adjusted by raising carefully until contact
ia felt between the head of the gage and the firing-pin retainer when the breech-
block is fully closed. To verify that contact has been established between the
headspace gage and the flrlng-pln retainer, the retainer shall be coated thinly
